Factory-integration bundle combines an 8 GA copper 600 W amplifier wiring kit with an AudioControl LC1i two-channel line output converter featuring 40 V speaker-level input handling
This package combines an AudioControl LC1i active two-channel line output converter with a Stinger SS600XS 8-gauge copper wiring kit rated for 600 watts. The LC1i accepts speaker-level signals up to 40 volts and provides preamp outputs up to 9.5 Vrms with adjustable gain. It is designed for drivers adding an aftermarket amplifier to a factory source unit without RCA outputs.
The LC1i features selectable input impedance at 20, 60, or 20k ohms plus a ground isolation switch to suppress noise. GTO signal sensing creates a 12-volt remote turn-on output automatically when audio is detected. The wiring kit supplies 8-gauge copper power and ground conductors, fuse holder, and terminals for a tidy installation. A compact chassis allows placement behind the dash or in tight cavities.
Verify your factory speaker wires can reach the LC1i mounting location and that the 40-volt maximum input covers your head unit's output. Confirm the 150-ohm preamp output impedance matches your amplifier's input requirements. Ensure the 120-milliamp current draw is acceptable for your vehicle's accessory circuit. Buyers who need more than two channels of conversion or a higher-voltage preamp output should consider a different solution.

The LC1i accepts up to 40 Vrms speaker-level input, rated for 400 W on the 20 k setting.
The kit includes 8-gauge copper power and ground wire sized for a 600 W system.
Use GTO signal sensing or audio sense on the speaker inputs; the unit then activates its 12 V remote output automatically.
